Ignition switch interlock
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
An interlock and security feature (ignition switch interlock) is mechanically connected to the ignition switch by a cable. The ignition switch interlock is controlled by the position of the lock cylinder in the ignition switch and by the position of the gear selector. This means that the gear selector must be in the P-position for the ignition key to be removed from the ignition switch. The ignition key must be turned to position I or II before the lever can be moved from the P-position. The ignition switch interlock is used only in combination with shift-lock.
